INJECTION STRETCH BLOW MOLDING DEVICE AND MOLDED PART HEATING DEVICE.

摘要

Provided is an injection stretch blow molding device wherein differences among the molding temperatures in (n) number of batches of blow molding operations are reduced when the number (N) simultaneously injection molded is blow molded by (M) ((M) = (N)/(n)) in the (n) number of batches in 1.5 stage process having both advantages of 1 stage process and 2 stage process. There is disclosed an injection stretch blow molding device having: an injection molding unit (10) which injection molds (N) (N is an integer of two or more) number of preforms; a cooling unit (20) which forcibly cools the (N) number of preforms carried out of the injection molding unit; a heating unit (30) which continuously carries and heats the (N) number of cooled preforms; and a blow molding unit (40) which divides the (N) number of heated preforms in (n) (n is an integer of two or more) number of batches to stretch blow mold (M) ((M) = (N)/(n): (M) is a natural number) number of preforms in (M) number of containers at a time.
